FRANK J'. CARLSON, 0F LOS ANGELES, CALIFORNIA, SSIGNOR T0 ALBERT E. BAIIBCDA AND LUCILLE KENNEDY, BOTH 0F BEVERLY HILLS, CALIFORNIA I mcmERA'roB Application led February 24, 1926. Serial `No'. 90,262.

My invention relates to incinerators, and the primary object of this invention is.: 1 mprovements over my application for incinerator filed June 6, 1925, Serial Number 35,341, the principal objects of'which are:

First, to provide an incinerator of this class with a pivotally mounted grate which will agitate the material being incinerated thereby facilitating combustion. Second, to provide a practical means by which the grate may be oscillated. Third, to provide a cleaning door large enough to permit the removal of wire, band iron, et cetera, from the grate and ashes from the ash pit under the grate. Fourth, to provide a means for swinging the cleaning door open and closed edgewise. Fifth, to provide a cleaning door with a draft door mounted thereon. Sixth, to provide a novelly constructed incinerator base and, seventh, to provide an incinerator of this class which is very simple and economical oi construction and operation, durable, and which will not readily deteriorate or get out of order. v

With these and other objects in view, my invention consists of certain novel vfeatures of construction, combination and arrangement of parts and portions as will be hereinafter described in detail, and particularly set forth in the appended claims, reference being had to the accompanying drawings on which similar numerals refer to similar parts throughout the several views and wherein:

Figure 1 is a fragmentary front elevation, showing by dotted lines the cleaning door tilted and the draft door raised. Fig. 2 is a sectional view taken on lines 2--2 of Fig. 1 showing some of the parts in elevation to facilitate the illustration, and Fig. 3 is a sectional view taken on lines 3--3 of Fig. 1.

In the preferred embodiment of my invention, 1 indicates a irebox which is mounted on base 2. A suitable grate structure 3 is formed with rocker arms 4 and 5 which rotate in slots 6 formed in the upper edge ofthe a 'cotter pin 8. When pressure isa plied to 'l pedal 7 the grate 3 willr pivot on roc er arms- The irebox is made of slabs of concrete y orother plastic material. The lower ends of the slabs are held together at theirv ends by alcollar 12 which is preferably made of band iron. The periphery of the firebox 1 at the lower end is smaller than the base 2, leaving a shoulder on which the collar rests. A cleaning door 11 is secured to this collar 12 by wing bolts 13, so 'that by removing one of said bolts the cleanin swung, facilitated'byhan e 14:, to the frag mentary dotted position shown on Fig. 1.

The cleaning door 1l is formed with an opening 15 and is covered by a draft door 16 which moves in slides 17, retarded by friction Contact, thereby making it possible to obtain the desired draft aided by draft openings 187 which draft openings also serve for adusting the position of cleaning door 11. Although I have shown and described a particular construction, combination and arrangement of parts, I do not wish to be limited to this particular construction, combination and arrangement of parts and portions but desire to include in the scopeof my invention the construction, combination and arrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In an incinerator, a base slotted at op-` door 11 may be ably connectedy to said cellar ever the open side of the base,` and a grate mounted in the upper edge of said base, saidzcleaning door being the full Width of said grate to facilitate cleaning of the same.

In testimony' whereof, I have hereunto set my hand at Los Angeles this 8th day of February, 1926.
